/* ============================================================
   CopyCopy docs — static documentation layout
   ------------------------------------------------------------
   Pure static HTML (no docsify, no markdown-at-runtime). Color,
   font, and spacing tokens come from site.css; this file adds the
   docs shell: sticky TOC sidebar, prose, code wells, and tables —
   all in the warm CopyCopy palette. Base resets, body, and the
   core .nav rules are inherited from site.css.
